Part of the label's Essential Collection, this shirt tunic by CO is designed to join the foundations of your edit. This oversized button-down shirt from Los Angeles label CO is crafted in a breezy cotton blend, with a hidden placket, three-quarter sleeves and a fishtail hem. Representing a pared-back approach whilst still retaining a sense of contemporary novelty, we love it paired with cropped trousers and slip-on leather sandals.
